Levee breaches occurred at a great number of places in Japan mainly due to overflow of huge flood. To increase the resistance of levee to overflow erosion, we propose a new type of levee in which concrete panels connected to geogrid layers reinforcing the sand cover the slopes and crest of the levee. Various laboratory tests were conducted to evaluate the resistance of this method to overflow erosion. The results indicated that 1) the sand backfill having a degree of compaction lower than about 85 % has low resistance to overflow erosion due to too large infiltration; and 2) the proposed type of levee can survive overflow continuing for a long duration showing that it can function effectively as a flood barrier.
